Infrazygomatic Crest Bone Screws in Orthodontics.

      Аннотация: Anchorage control acts as the cornerstone of the orthodontic force system. Anchorage is provided by the teeth that resist the forces of reaction generated by the active components of the appliance. So, any unwanted tooth movement must be controlled; otherwise, the underlying malocclusion will worsen during tooth alignment and to overcome this problem, skeletal anchorage has been increasingly popularised into orthodontic treatment. Melson, Peterson, and Costa used the concept of gaining anchorage from infra zygomatic crest since 1998 for intrusion and retraction in a partially edentulous patient using zygomatic ligatures.
